I really don't even know how to start doing this problem.
I understand PV=nRT and I understand that if either T, V, or P is kept constant, then the other 2 change at the same rate, and I understand that if either T, V, or P is kept constant while the other two change, then the system experiences a change in heat. I also understand that the internal energy is kept constant and that internal energy = heat - work. However I do not know how to relate the change in temperature to a change in heat. Can somebody please walk me through this?
Here is a diagram to better visualize the problem.
My homework question asks to find the temperature at point c
I have already calculated that n=0.41 and that the pressure at point b is 2.01966 atm
You do not need to solve for c, just please tell me how.
Okay so I couldn't handle it anymore and I just looked at the answer which happened to be 810J. This make me even more confused. Where did the extra 110J of energy just appear from?
